Large civil engineering projects: dams, tunnels, excavations, in Italy and worldwide
Monitoring systems for dams and large scale civil engineering projects in general have always been the areas of greatest interest to the Pizzi Instruments team. We were established over 35 years ago, continuing the activity of an important Italian company specialised in instruments for monitoring dams: Officine Galileo of Florence.
Amongst our works, we boast the provision of the monitoring system of the world’s highest dam: Gibe III in Ethiopia. Our instruments have been used for the structural monitoring of tunnel entrances, excavation areas, and tunnels and buildings surrounding excavation areas.
Thanks to our specific experience in this field, our instruments have been requested to monitor the New Foster Station in Florence and the excavation site of the underground crossing of Florence (High Velocity Project). Thanks to our solutions, all important parameters are monitored in real time, with accuracy and precision and all tests required by Italian and international technical regulations are executed.
From 1997 to today, the Pizzi Franco company has periodically signed a series of contracts with the Ente Acque della Sardegna both for scheduled maintenance and for the new supply of monitoring and control instrumentation installed at the dams managed by the Directorate of the Dams Service of the Authority. .
For several years, the Pizzi company has been periodically revising the monitoring equipment supplied and installed at the dams managed by the Mediterranea delle Acque water supply service.
In 2007, the Pizzi company received an important order from the dam managing body, JP Elektroprivreda of Mostar, for the supply and installation of instrumentation that allowed the automation and implementation of the monitoring system installed there.
Pizzi Instruments S.r.l. received and executed the first order in partnership with DDWay Srl, as General Contractor towards the Ministry of Infrastructure and Transport – Dams General Management, concerning the design, supply and installation of automatic monitoring systems and hydrological emergency control .
Gilgel Gibe III is a dam, currently nearing completion, about 243m high in RCC (Roller Compacted Concrete). Once completed, the dam will be connected to a hydroelectric power plant on the Omo River and will represent the largest hydroelectric power plant in Africa.
The project is situated at about 500 km north west of the Addis Abeba capital in the region of the Benishangul – Gumaz (Ethiopia), along the Blue Nile River.
Pizzi Instruments intervened in the final phase of the dam operation by providing the supply and of the commissioning of vibrating wire rod extensometers and of a hydrographic station necessary to monitor the hydrographic processing of the dam.
On May 2014 the Sicily Region requested Pizzi Instruments to carry out a series of inspections on the monitoring instruments installed on the dams directly managed by the Sicilian Departmente of Energy and Public Utilities.
In 2015 Pizzi Instruments receives from SE Hydropower of Bolzano the first contract for the supply of n. 3 laser telependulums – model LAC3000. In 2016, the customer, fully satisfied with the delivery, proceeded with the order of three additional laser telependulums – model LAC3000.
The Valfabbrica dam on the Chiascio river, with its availability of 145 million cubic meters per year, is able to meet the drinking water needs of the city of Perugia and other smaller cities.
Lake Disueri is an artificial lake located in the municipality of Gela, in the province of Caltanissetta. The lake is located 150 meters above sea level, is 3 km long and 1 km wide at its widest point. Its maximum depth at full reservoir is 34 m, with a volume of water of 14 million cubic meters.
